About Simon - the electronic memory game
Simon is one of the best-known electronic games. Four coloured buttons light up in a sequence with a tone each, and you have to repeat it. It looks simple, but every round makes the sequence one step longer.
Where Simon comes from
Simon was invented by Ralph Baer and Howard Morrison and launched in 1978. It was inspired by the arcade game Touch Me and named after the children's game Simon says. The round shape with four coloured quarters and a dark centre became a classic toy of the late seventies and eighties.
How the game works
The game plays a sequence of buttons, each with its own tone. You repeat it. If you get it right, the game plays the same sequence again with one more step at the end. A wrong button ends the game, and on the harder levels waiting too long does too.
Why it is good for your memory
Simon trains working memory, the short-term memory you use to hold a phone number in your head. Most people can hold about seven items at once, so long sequences need tricks such as grouping, naming the colours or humming the tune.
Tips for longer sequences
Say the colours quietly to yourself, or remember the tones as a little tune. Split the sequence into groups of three or four. Do not rush: on Easy you have as much time as you need to think before each press.
